Description
Summary:We report on the observation of magnetic dipole allowed transitions in the well-characterized A 2 capital sigma + - X 2 capital pi band system of the OH radical. A Stark decelerator in combination with microwave Rabi spectroscopy is used to control the populations in selected hyperfine levels of both Lambda -doublet components of the X 2 capital pi 3/2, v = 0, J = 3/2 ground state. Theoretical calculations presented in this Communication predict that the magnetic dipole transitions in the A 2 capital sigma +, v = 1 arrow left X 2 capital pi , v = 0 band are weaker than the electric dipole transitions by a factor of 2.58 103 only, i.e., much less than commonly believed. Our experimental data confirm this prediction.
